Understanding how coastlines change plays a key role in developing strategies for coastal protection and sustainable resource utilization. This study investigates the temporal and spatial changes in the Bangkok Bay coastline, Thailand, using remote sensing and GIS techniques from 1989 to 2024. The historical rate of coastline change for a typical segment was analyzed using the EPR method, and the underlying causes of these changes were discussed. Finally, the variation trend of the total shoreline length and the characteristics of erosion and sedimentation for a typical shoreline in Bangkok Bay, Thailand, over the past 35 years were obtained. An overall increase in coastline length was observed in Bangkok Bay, Thailand, over the 35-year period from 1989 to 2024, with a net gain from 507.23 km to 571.38 km. The rate of growth has transitioned from rapid to slow, with the most significant changes occurring during the period 1989\u20131994. Additionally, the average and maximum erosion rates for the typical shoreline segment were notably high during 1989\u20131994, with values of \u221221.61 m\/a and \u221255.49 m\/a, respectively. The maximum sedimentation rate along the coastline was relatively high from 2014 to 2024, reaching 10.57 m\/a. Overall, the entire coastline of the Samut Sakhon\u2013Bangkok\u2013Samut Prakan Provinces underwent net erosion from 1989 to 2024, driven by a confluence of natural and anthropogenic factors.<\/jats:p>","DOI":"10.3390\/jimaging12010021","type":"journal-article","created":{"date-parts":[[2026,1,2]],"date-time":"2026-01-02T09:56:23Z","timestamp":1767347783000},"page":"21","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Multi-Temporal Shoreline Monitoring and Analysis in Bangkok Bay, Thailand, Using Remote Sensing and GIS Techniques"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-7846-6372","authenticated-orcid":false,"given":"Yan","family":"Wang","sequence":"first","affiliation":[{"name":"Faculty of Engineering, Rajamangala University of Technology Krungthep, Bangkok 10120, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-5537-7995","authenticated-orcid":false,"given":"Adisorn","family":"Sirikham","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Rajamangala University of Technology Krungthep, Bangkok 10120, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7199-6402","authenticated-orcid":false,"given":"Jessada","family":"Konpang","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Rajamangala University of Technology Krungthep, Bangkok 10120, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunguang","family":"Li","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Jiangsu College of Finance and Accounting, Lianyungang 222061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"129","DOI":"10.1016\/S0964-5691(96)00059-2","article-title":"Defining and Interpreting Shoreline Change","volume":"32","author":"Camfield","year":"1996","journal-title":"Ocean Coast.
